Error in the process of integrating MS Sharepoint 2019 SE and Onlyoffice Docs Enterprise (New-SPWOPIBinding)

An error occurs during the integration process between MS Sharepoint 2019 SE and Onlyoffice Doc. According to the integration instructions, I take the following steps:

  1. Set-SPWOPIZone -Zone “external-http”
  2. Remove-SPWOPIBinding -All:$true
    As a result: SPWOPIBinding created earlier in the process of integration with MS OOS was removed
  3. successfully deployed the ONLYOFFICE Docs Enterprise Edition server (docker). Chek - works correctly. “To enable WOPI, set the wopi.enable parameter in the Document Server config to true” - YES, done
    Check - - OK
  4. Next I enter the command (SP 2019 server) New-SPWOPIBinding -ServerName -AllowHTTP
  5. I get the error: New-SPWOPIBinding: One or more of the WOPI bindings specified in New-SPWOPIBinding already exist. The operation has been cancelled.
  6. I check just in case: Get-SPWOPIBinding. The result is empty. no SPWOPIBinding created.

I don’t understand how to fix this? if I try to return integration with MS OOS again, everything works correctly. The problem is only with Onlyoffice Docs integration
